Calling an API returning two variables, "allowed" which is a boolean and "message" which is a string.
It errors out

Now, transforming the boolean to an integer, it works :

NB : The boolean works just fine if the API returns 0 instead of false :

The CallBack's OnSuccess method doesn't change between the two screenshots.

My OnConnectData which cause the error is :

class OnConnectData
{
    bool allowed;
    string message;
}
